The Perils of Flooded Lead Battery Discharge Below 50% and Partial State of Charge

Depth of Discharge (DoD) is used to describe how deeply a battery has been discharged. Cycle life is the number of times a battery can be cycled to a certain point before the battery will reach the end of its usable life. There is a direct relationship between the DoD and the cycle life of a battery.

Battery Bank Sizing

There are a lot of factors that go into determining the appropriate sized battery bank for a boat, and no hard and fast criteria. However, there are some general guidelines that can help in setting up a bank of batteries that will provide enough power for the DC systems on board without sinking the boat or your finances.

Battery Monitors

A boat’s battery bank is at the heart of its DC electrical system and the banks state of charge (SOC) is critical information. Not only is it important to know how much energy remains stored so you do not deplete the bank and no longer have the power needed to run boat’s services, but it is also necessary information to maintain the batteries in good health to maximize the number of cycles possible from the bank.

More Energy: Reducing Your Power Needs

Anyone that has ever lifted a battery knows that they are quite heavy and bulky. In many cases the demand for power on a boat is greater than the space that is available to hold the battery banks. In these instances...

Tips for Installing Large Battery Banks

When installing a large battery bank there are a few things we need to take in consideration both for safety and...

Battery Banks and Loads

How Simple DIY Battery Connection Checks Can Help Your Boat

Are your battery connections the best they can be? Here are some simple do-it-yourself checks that you can perform to help maintain the connections to the heart of your boat. These are simple checks and tasks that take no more than 10 minutes and will lead to peace of mind when you are at sea.

Mixing Battery Types in a Single Bank

You have probably heard that it is bad to mix battery types and ages in a single bank, but you may not know why. A simplified answer is that the stronger batteries will always be charging the weaker batteries. This is true, but let's take a closer look at this problem.

Is Your Boat Wired to Melt?

On a client's boat recently, we saw that the wiring was chaotic to say the least. But take a closer look at the two 3 conductor 14 AWG AC wires which go up to the main DC distribution panel.

Charging More Than One Battery Bank: The PYS Recommendation

Today, many recreational and leisure boats have more than one battery bank and proper charging systems can get fairly complicated. There is no one solution for every boater. It not only depends on the style of boat, but also on how the boat owner uses his or her boat.
